V Application March 22,1944seyia1N0-527592 oclaims. (C1. 294-67) ful in lifting a load of piled-up tubes, or bars.,

from a table, orother load supporting means, by being adapted to` be swung under theload so supported and then manipulated to embrace 4the load toprevent piled-up tubes, or bars, from shifting as they,as a lo'ad, are raised from the previous supporting means.V In order to so raise v a plurality of piled-up tubes, or bars, without undue shifting of the same, which might damage their finish or distort them, it is contemplated as an objectV of this invention tofprovide in the Agrab structure a side supporting member whichisvarranged to be swung, 'or rotated, to adapt Ait to be turned latwise to permit it to be slid under the `load and then turned upwardlyV into a loadbra-cing position.

' Another object of this invention is to provide a grab having a series of stationary members, or arms for bracing one side of a pile of tubes, or rods, and a Vseries of members, or arms, which are adapted to be turned in unison to `permit them to be swung transversely under the load and then be turned upwardly to brace the other side of the pile of tubes, or rods. a

` A further object of this invention is to provide an improved stock handling grab which will be relatively inexpensive to manufacture,` simple in construction, compact, and very` efcient and durable in use. u

With the above and vother objects in,` view, which will appearas the .description proceeds, there has been illustrated in the accompanying drawings a form in which the invention may be conveniently embodied in practice.

In the drawings:

Figure 1 is a broken top plan view of astock handling grab embodying the features and principles of this invention;

Figure 2 is a brokenfront `view of the grab shown in Figure 1;

Figure 3 is `an end view of the grab;

Figure 4 is an enlarged broken view looking in the direction of arrow 4 in Figure 2;

Figure 5 is anenlarged sectional view taken on the line 5-5 of Figure 2;

Figure 6 is an enlargedbroken view looking in the direction of arrow 6 of Figure 3; and

Figure "I is a view showing an arrangement wherein an electric motor is adapted'to actuate certain operable parts of the grab.V

Referring now to the drawings wherein like reference numerals designate like parts throughout Vthe several views the numerals II and I2, see Figures 2 and 3, denote, in dotted linespspaced apart legs of a tube, or rod, supporting table, or the like, having laterally extending and vertical- -ly spaced apart cross-bars I3 and I4, and upwardly and outwardly extending arms I5 and 'I6 adapted to support and hold a pile of a plurality of tubes, or bars, I1. The legs II and I2 are tied together by lengthwise extending front and rear beams I8 and I9 respectively which are spaced from and below the cross-bars I3 to form a space therebetween. It is obvious that the cross-bars I3 formvthe top of the table, or supporting means,'for the tubes, or bars, I1, and

`that the angularly disposed arms I5 and IB form the Iembracing means to maintain the pile of tubes, or bars, I1 in a determined desired shape.

'The stock handling grab, in accordance with the features and principles of this invention, is adapted to be slipped under the pile of tubes, or bars, I1 and, without disturbing the shape of the same, to raise the same from the table, or sup- `porting means, and transport it to4 another location. The grab illustrated includes a carrying member having crane hook engaging loops 2I secured-thereto whereby the grab may be lifted and moved from one position to another, and being composed of adjacent channel beams 22 `and 23 between which the loops 2| are disposed. In this instance a counterbalancing beam 24 is provided 'spaced from the'carrying `beams 22, 23 and secured thereto by cross-bars 25 and 26'.V

Depending from the' carrying beams 22, 23 are a lplurality of tube, or bar, engaging carrier arms 21?herein shown as each being composed of a short member 28, an angular outwardly disposed member 29, a vertical member 3I,'and a horizontal member 32, the last member 32 forming the I ybase of the arms 21 and upon which the tubes, or

bars, I1 will be supported after being engaged thereby during the operation of a grab. A supplemental tube, or bar, lengaging member 33 is provided and suitably secured, as by welding, to the base member 32. The member 33 extends upwardly from the base member 32 substantially at the 'same angle as 4the table arm I5.

A rod 34 extends along and is rotatably supported from each base member 32 in suitable bearings 35 and 36 secured to said base member. The inner` end 31 of said rod 34 yis bent away from the remainder at an angle substantially the same as the angle of the table arm I6. The rod end 31 and the member 33 with the base member 32 form a support, or cradle,

to embrace the pile of tubes, or bars, |1 of determined desired shape. An operating bar 38 has its lower end secured to the outer end of at least one of the rods 34 and extends substantially at right angles therefrom. The bar 38 is provided with a handle 39 at its upper end by which it maybe swung to rotate the rod 34 in its bearings 35 and 36. The handle 39 vis pivoted to the bear 38 to be rotated to cause a latch member 4| to be swung over the'end of a latch catch 42, secured to the adjacentvertical member 3| of the carrier 21, to prevent the bar 38 from inadvertently swingingV out of its `vertical position. When the bar 38 is in its vertical position, as shown, the rod end portion .31 extends upwardly in tube, or bar, |1 embracing position.

As shown in Figure 1 a plurality of carriers 21 are provided and each of the rods 34 of the end carriers is provided with an operating bar 38 and handle 39. 'I'he rod 34 of each of the intermediate carriers 21 have a short bar 43 (see Figure 2) secured to the inner end thereof, which bar 43 extends substantially at right angles t the associated rod 34. The upper end of veach bar 43r and the bars 38 are connected by a .rod 44 so that they will-swing in unison, the rod 44 being pivotally connected to each bar by a bolt 45.

In order to limit the amount the grab of this invention is lowered and to insure that it is lowered the ysame amount each time it is used with tables, or other supports, of the same height from the door, provision is made to stop the grab in its downward movement bymeans of a vertically adjustable stop bar 46. The bar 46 is slidably secured to one of the carriers 21 by being guided at its upper end in a clip 41 secured to the vertical member 3|, and a clamp screw 48 extending through a slot' 49 provided in the bar 4B and screw-threaded into the member 3 The arrangement shown in Figure 7 whereby the connecting rod 44 may be actuated by an electric motor includes a motor supporting bracket 52 having a gear pinion 53 on its shaft the teeth of which meshes with the teeth of a gear quadrant 54 pivoted to a bracket 55. The brackets 52 and 55 are herein shown secured to and extending from one of the end arms 21 ofI the loa-d carrying grab. The rod 44 is pivoted at 56 to the quadrant 54 in such a manner that rocking movement of the quadrant 54 by the motor5| will impart the required movevment to the rod 44 to swing the bars 38 and 43 and through them to swing the rod ends 31 into the desired horizontal position for the purpose above described.

In operation the grab of this invention is low- `ered with the rod end portions 31 disposed in a horizontal position'as indicated in dotted lines in Figures l and 2. When the rod portions 31 are in a horizontal position, the bars 38 and 43 are in a horizontal position and the bars 38 rest upon stop lugs 51 extending out from the vertical members 3|. The grab is lowered until the lower end of stop bar 46 strikes the floor and is then moved horizontally to dispose the .base members 34 in under the load of tubes, or

rods, supported on the table, or like support.

When the grab is in position under the load, sce Figure 3, the operating bar 38 is swung upwardly to dispose the rod portions 31 in back of the load. The swinging movement of the bars A 38 and 43 is limited by stops 58 which extend out from and are secured to the adjacent vertical members 3| and which are herein shown as supports for the latch catches 42. The latch member 4| is now swung into latched position with the latch catch 42, see Figure 5, and the grab is operated by its supporting crane to engage and lift the load from its support.

l By providing in a graba plurality of rod end portions 31 which are swingable from a .horizontal position extending lengthwise of the tubes, or rods, of the pile, permits the use of such a grab to engage and lift loads from the top of a table, or other support, herein beams I3, which is spaced closely from the oor, or wherein the table top is spaced closely from reinforcing beams such as |4, I8, and 9, which in turn are supported from the oor by legs and |2. I'he adjustable stop bar 46, when once adjusted to the table, or other support, supporting the load, locates the proper position of the grab whereby it may be swung under the load without interference, is clamped in place and assists the operator of the crane in the operation of the grab.

While there has been disclosed herein one form in which the invention may be embodied in practice it will be understood that the novel features and principles of this invention may be embodied in other specic forms without departing from the spirit and essential attributes thereof, and it is therefore desired that the present embodiment be considered in all respects as illustrative and not restrictive, reference being had to the claims rather than to the foregoing description to indicate the scope of the invention.
